From the Research

For a pediatric patient with a lip laceration, I recommend gargling with warm salt water 3-4 times per day for 5-7 days or until the wound has healed. The salt water solution should be made by dissolving 1/2 teaspoon of table salt in 8 ounces (1 cup) of warm water. Have the child swish the solution gently around the mouth for about 30 seconds before spitting it out. This should be done after meals and before bedtime to keep the wound clean. Salt water works as a gentle antiseptic that helps reduce bacteria in the mouth while promoting healing by reducing inflammation.

Some key points to consider when managing a lip laceration in a pediatric patient include:

  • Ensuring the child avoids spicy, acidic, or hard foods that could irritate the wound
  • Monitoring for signs of infection, such as increased redness, swelling, pus, or fever
  • Seeking medical attention promptly if the laceration is severe, doesn't improve within a week, or if the child is unable to eat or drink properly
  • Considering the use of topical anesthetics, such as Laceraine, to help manage pain and discomfort during the healing process, as suggested by a study published in 2023 1
  • Keeping in mind that wounds heal faster in a moist environment, and occlusive or semiocclusive dressings may be beneficial, as noted in a study from 2017 2

It's also important to note that the management of lip lacerations may vary depending on the individual case and the healthcare provider's professional judgment. However, in general, a conservative approach with good wound care and monitoring for signs of infection is often the best course of action. As stated in a study from 2021, treatment of lip infections caused by Staphylococcus aureus may require surgical intervention and/or antibiotics, and immune compromise and antibiotic resistance should be considered in patients with similar presentations 3.
